摘要
目的探讨不同运动负荷对大鼠免疫功能的影响。方法 40只 SD大鼠,随机分为对照组、 45min组、 90min组、 150min组和力竭组,进行无负重游泳训练 8周,每周 6次。测定腹腔巨噬细胞诱导型一氧化氮合酶 (iNOS)和血液中表面受体细胞 (CD)CD4+ /CD8+变化。结果 150min组及力竭运动组腹腔巨噬细胞 iNOS与对照组相比显著上升( P< 0.05),且力竭组显著高于 150min组。血浆 CD4+ /CD8+的比值在 90min组、 150min组显著上升( P< 0.05),而在力竭组则显著下降。结论适量运动引起的腹腔巨噬细胞诱导型一氧化碳合成酶 (iNOS)活性提高,增强机体的细胞免疫,增强机体的抗癌能力。而力竭运动引起的腹腔巨噬细胞 iNOS的活性增强,可能与大强度运动引起的细胞免疫抑制有关。
Objective To study the adjustment mechanism of different workload exercise’ s influence on immune system.Methed we exemine activity of the iNOS in resident peritonerl macrophage and the level of CD4+ /CD8+ in plasma.Result plasma CD4+ /CD8+ of 90 minute and 150 min group are significently increase(P< 0.05),iNOS activity in peritoneal macrophage of 150 min and exhausting group increase (P< 0.05).Conclusion iNOS activity in peritoneal macrophage of moderate exercise increasing enhances the capabillity of anti- cancer.The iNOS activity increasing in exhausting group may relate to the depression of cellular immunity.
